Hm...I'm not sure her reaction to what just happened her was very realistic. You showed that she didn't want anyone to know what had happened to her which is very likely in real cases, but you didn't explain why. It could've been because she felt guilty or ashamed or idiotic for letting that be done to her. It could've been any number of reasons.

Also, I help instruct women's self defence courses and I've talked to alot of victims of sexual assault and read alot into it and I know that from what I've seen women who have been sexually assaulted often are terrified of men afterward. This is true even if they knew them prior to the incedent. They usually will not allow any man, even other women, to touch them without flinching away. The way your character let her boyfriend touch her and carry her around wasn't very realistic.

Your story is great so far! Maybe a little bit of research and it will be even more amazing. I'm really enjoying it, I'll be waiting for the next chapter as always :)
